Here are some more sketches of my cat character.I have been trying out different expressions as well as trying to get the mouth movement correct for certain words. The most important mouth movements are all of the vowels - A, E, I, O, U and the important consonants include B, M, P, F, T, V. The mouth positions also affect the eyes, eyebrows and cheeks so it is important that the whole face works in correlation so that it translates the emotion.
